To all whom t may concern.'

Be it known that I, HENRY II. AnnsoN,

a ycitizen of the UnitedStates, andaresident of Fairmont, in .the countyof rMartin .and State et Minnesota, have .invented 'a certain new andusetul Burglarproot Device, :of which the following .is specification.

The object .of my invention is `totprovide :a burglar prooi device `oftvery ,simple and eli'icient construction.

More particularly, it is :my objectto :provide a device of the generalkind undericonh sideration, whereby fa closure Amember 'for a vaultfdoor and :a closure Vmember ier fa .cash box are so arranged that uponthe closing of :a switch, a -cireuit'may be closed `or qreleasing Ytheclosure devices for zpreventing access to .the rvault .and fthe Vcashbox.

iWith these and other ebjects in wiew, :my 2o rangement and combination.of the aricus parts ot' my device, whereby the Iobjects contemplatedare attained, as hereinafter zmore full-y set forth, pointed out in ymyclaims, e and 'illustrated in fthe accompanying idrawings, in which:

Figure 1 showszan inside or .rear elevation ot a bank vault adoor -orfthe :like A.equipped with :a lclosure member embodying my in- `Sievention.

Figure 2 shows `a perspective view tot a portion :ot a bank counter4having :thereon a cash boX equipped with my invention.

Figure 3 shows a vertical, sectional yview 3;, through the cash boX.

VFigure 4 shows ,a detail, sectional Aview taken on the "li-ne 1 1 ofFigure 3.

Figure 5 showsfa-detail,sectional view of the locking device for thedoor closure anember; and

Figure 6 shows -a diagrammatic view of the electrical connections.

In the accompanying drawings, I 'have used the reference numeral 10 toindicate generally `the wall of Ethe *bank vault .or the like, in which:is provided -a door opening 11. On the inside of the vault andspacedlaterally from the door 4opening on opposite sides thereof are mountedupright bars 12.

Pivoted to the bars 12 are laterally projecting members 13. f I provideagplurality ot the members 13 Vfor each bar 12. Pivoted to each set ofmembers 13 are spaced closure bars 111, 15, and 16. Pivoted toinvent-ion consists in the construction, .ar-v

each closure Ibar 16 is a Alocking bar 17 eX- tende'd 'through a guideor keeper 18 on the bar i12.

Mounted on `the bar .12 lb'e'low fthe locking bar 1-7 :is a A,pin 19`and in ythe lower edge or the lbar 17 isa notch 20. In ithe upperedge'ofzthe'bar 17 .is a notehl.

Above the locking bar 17 is a swinging pawl `or `locking member .22.

W hen the closure. device, .just described, is Lopen, the members 13 areinclined upwardly, Vas `shown inFig-.ure .'1, and the linem bier 417 `isinclined downwardly eand laterally as show-n in said ligure.

It will `be seen that the closure .device tends :to drop by gravity toclosedpiositinn, and when rit does so drop, the members '17 will slidevin the guides 418, iunti'l lthe notches 20 register with the pins 19,whereupon :the pins 19 will enter 4the notches 2O and the locking pawls22 will swing downwardly with their ltree ends received in the not-ches21, so that the bars 17 `can lnot zbesraised, lexcept Eby the use of aspecial vtool or `by fcnttfing them in two.

At'bove the ydoor Lopening 11 are two bars 22a ,pivoted together atadjacent ends, as 4at 23, and having near their -outer ends,elongatedfslotsl24, in which are received rpins2. 3V-hen `the lclosuremembers are raised, .as shown in Figure 1, the bars 22a are arrangedsubstantially in alignment horizontally with their ends abutting againstthe upper ends of the -members 16, between the members 16, as shown inFigure 1.

'Ihe friction of the .parts will hold the closure member open. However,rowing Eto the `fact that the great weight of `the bars 22a 'is betweenthe pins 25, the central 'portions of the bars 22 will tend vto dropdownwardly, when their trictional engagement with the member 16 isreleasedor when forced downwardly Vin any way.

lVhen the adjacent ends of the bars 22 are moved downwardly, their*outer ends swing upward-ly and clear the members 16, whereupon theclosure member vwi-ll'd'rop by gravity to locked position.

Above the bar-s 22 is a guide 26, -in which is :mounted a. weight 27having za head 2S. A trigger 29 is pivoted adjacent to the head 28 andhas a projecting ringer -or the like 30, which can be made to standbelow la portion of the head 28 for holdingthe head 28 in its raisedposition.

CIJ

Adjacent to the trigger 29 is a solenoid 31, having an armature 32. Thesolenoid is connected in an electric circuit by means of wires 33 and 34with a source of electrical energy 35 and a switch 36.

I have shown a portion of a bank counter 37 on which is placed a cashbox 38, preierably made of steel having an inclined sliding door 39mounted between guides 40 and 41 at the sides of the cash box.

The rear guide 41 is in the term of a plate or partition, which extendstrom the upper part of the box downwardly and iorwardly, as shown inFigure 3.

lVhen the sliding closure member 39V is down, the cash box is closed,and when it is up, ready access can be had to the interior of the cashbox.

In the guide and closure member 41 is an opening 42 through whichprojects a tinger 43 on a Vtrigger device 44 pivotally mounted ontheinside ot the cash box.

On the inside of the cash box adjacent to the trigger member 44 is asolenoid 45, having the armature 4G. rthe solenoid 45 is connectedbywires 4T and 48 with the battery 35 and a switch 49. The switch 49 isconnected with the wire 33 by means of a wire 50.

As many switches may be provided as is desired.

In the diagram shown in Figure G, I have shown a switch 51 located in abuilding at a distance from the bank. The switch 51` is connected bywires 52 and 53 with the wire 33 and the switch 36. The wire 53 isconnected by a wire 54 with the wire 48.

Y Mounted adjacentto the side of the boX 38 in a recess 55 by means ofa. pivot pin 56 is a catch 57, having a catch member or face 58 and abeveled face 59.

In the side edge of the sliding closure member 394is a notch 60. Thecatch member 57 is held in substantially upright position, as shown inFigure 4 by means of an arm 61, which engages a flat spring G2.

In the rear surface of the sliding closure member 39 is a small notch 63arranged to receive the linger 43 when the member 39 is raised, as shownin Figure 3.

In the practical use of my improved burglar proof device, the closuremember :tor the bank door is raised as shown in Figure 1. The closuremember 39 is raised, as shown in Figure 3.

In case a burglar should enter the bank, any employeeffor otiicer, whois near a'switch can actuate the switch for closing the circuit.Switches can be placed on the floor or behind the counter or wherever itmay be desired.

Then any one of the switches, for in stance the switch 49, is operated,a circuit will be closed. Y

vWhen the switch 49 is operated., a circuit will be closed from thebattery 35 through the wire 4'?, the solenoid 45, the wire 48, the wire50, the wire 33, the solenoid 31, the wire 34 and back to the battery.The armatures ot' the solenoids will be energized.

lVhen the armature 46 is energized, the trigger 44 will be drawn towardthe armature 46, which will draw the pin 43 from the opening 63. Theclosure member 39 will engage the beveled edge 59, so that the catchmember 59 will permit the closure member to slide to closing position,where upon the spring 62 will cause the engaging member 58 to enter thenotch 60 for locking the closure member `39.

Wlhen the armature 31 is energized, the

trigger 29 will be drawn out of engagement with the head 28, whereuponthe weight 27 will drop upon the adjacent portions of the bars 22aforcing them downwardly and forcing their outer ends upwardly out ofengagement with the bars 16.

Thereupon the closure member 17 for the vault door will drop by gravityand be locked.

Thereafter the burglar will be shut out from access to the vault and thecash box.

It will be Vseen that my invention may be applied in a great variety ofways to fit the circumstances.

Switches may be placed in the `manner and locations desired.

The operation of the closure member for the vault door would prevent theburglar 'from locking the employees of the bank in the vault.

The cash, which the bank employees are obligedto have on thecounter forconduct ing current business should be kept in the cash box 38 in a cashdrawer or the like,

which can be readily placed in the cash box or removed therefrom atnight and placed in the vault. i

Some changes may be made in the arrangement and construction of thevarious parts of my device, without departing from the essentialfeatures and purposes of my invention, and it is my intention to coverby my claims, any modified forms of structure or use of mechanicalequivalents, which may be reasonably included within their scope.

I claim as my invention:

1. In a device of the class described, a pair of foldable closuremembers, adapted when open to stand in raised positions where they tendto drop by gravity to position forming a closure, a pair of bars pivotedtogether and piv-otally and slidably supported near their outer ends, sothat when in substantial alignment their outer ends are frictionallyheld between the upper ends of the oldable closure members, a weightabove the bars between their pivot supports, a trigger for supportingsaid weight, and an electric circuit including a solenoid and a lUUswitch, whereby when the switch is closed the solenoid Will be energizedfor moving the trigger for releasing the Weight.

2. In a burglar proof equipment, a clo sure device comprising a pair ofbarred gate members, each consisting of an upright member designed to besecured to a Wall or other support, a plurality 'of cross bars pivotedto said upright bar, a plurality of spaced upright bars pivoted to saidcross bars, a notched latching bar pivoted to one of the last-namedupright bars, and a pin adapted to coact With the notched bar forholding the gate in closed position.

3. In a burglar proof equipment, a closure device comprising a pair oiibarred gate members, each consisting of an upright member designed to besecured to a Wall or other support, a pluralityT of cross bars pivotedto said upright bar, a plurality of spaced upright bars pivoted to saidcross bars, movable means for holding said gate in open collapsedposition, means for causing releasing movement of said last means,

and means for automatically latching said 25 gates upon their movementto closed position.
